LiftMaster CAP4AP Smart Access Controller 4-Door

Outdoor myQ Community Access Control for Gates and Doors

The LiftMaster CAP4AP Smart Access Controller is a cloud-managed access control controller for up to four gates or doors. Designed for myQ Community access systems, it gives property managers, installers, and facility teams a compact controller that can be mounted closer to the controlled opening instead of routing every wire back to a central equipment room.

The CAP4AP is built for gated communities, multifamily buildings, commercial properties, industrial sites, amenities, side doors, utility rooms, parking access points, and perimeter-controlled entrances. It supports card, transmitter, RFID tag, mobile credential, Wiegand, and OSDP reader-based access control through the myQ cloud platform.

This controller supports Wi-Fi, Ethernet, and PoE connectivity, with cellular connectivity available through compatible external modem solutions. Local configuration can be performed through the built-in Wi-Fi hotspot setup page, while database management, access schedules, event monitoring, and system administration are handled through myQ Community.

The CAP4AP includes four relay outputs, two Wiegand inputs, support for up to four OSDP readers, monitored inputs, local event storage, real-time status indicators, anti-tamper alarm capability, and an outdoor-rated polycarbonate enclosure. It is intended for professional access control installations where gates, doors, readers, locks, sensors, and credentials need to be managed through one connected platform.
